Letters Patent No. 105,003, dated Juty 5, 1870.

IMPROVEMENT IN RINGS FOR SECURING HOSE TO COUPLING-S.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern tion thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this speci- I fication.

Figure 1 represents an edge view of my improved hose-clamp or ring.

Figure 2 is a side view of the same.

Figure 3 is a detail perspective view of the same.

Similar letters of reference indicate corresponding parts.

This invention has for its'objeet to provide a ring or clamp by means ofwhich hose of suitable kind can be secured to the metallic coupling.

The invention consists in the construction of a clamping-ring withgrooved surface, and projecting teeth or' ears, whereby it will becomeentirely selffastening, the ears being bent into the grooves for holdingthe ends together. Heretofore, screws or bolts were employed for lockingthe ends of such rings together. They were not only diflioult toapply,but also liable to wear loose, and necessitated the use of projectingears, which made the entire coupling cumbersome, and were apt to becomebent out of shape,

or to break entirely. By my invention all-these difliculties areentirely overcome.

A, in the drawing, represents the ring for clamping the hose B to thecoupling 0. t

The ring A is made of suitable metal, and of the required size. Its faceis near one end provided with transverse grooves or notches a a.

From its edge project, near the other end, ears b I).

The end which carries the ears I) is to be below or on the inner side ofthe grooved end, so that the ears,

when bent over the outer end, will enter the grooves a, and thereby lockthe ends together.

The grooves a may be sunk into the face of the ring, or are formed byprojecting ribs 0 c.

This fastening is extremely simple, and does not require additionalscrews or devices, which are apt to be lost or misplaced. Ribs (Z (I maybe formed on the ring, to allow the application of tongs, for drawingthe ends of the ring together during application.

Having thus described my invention,

I claim asv new and desire to secure by Letters Patent- Theclamping-ringprovided with the grooves (g and projecting ears I), as setforth.
